Alpha Resonances in (13)C Excited by the (9)Be ((6)Li,d) Reaction

The (9)Be((6)Li,d)(13)C reaction was used to investigate alpha resonant states in (13)C up to 13 MeV of excitation. The reaction was measured at a bombarding energy of 25.5 MeV employing the Sao Paulo Pelletron-Enge-Spectrograph facility and the nuclear emulsion detection technique. The resolution of 50 keV allowed for the separation of the resonant contributions to the known 7/2(-) at 10.753 MeV and (5/2(-)) at 10.818 MeV (13)C states. The alpha resonance seen at the (3 alpha + n) threshold was not previously reported. The experimental angular distributions are presented in comparison with DWBA predictions.
